Suresh Srinivas updated HDFS-1936:
----------------------------------

    Attachment: HDFS-1936.1.patch

Todd, here is the patch I have so far. This does not fix the upgrade failure yet. Can you
look at this early version of the patch, since it is not likely to change when upgrade issues
are fixed.

Some of the namenode logic that depends on layout version is broken because of this. Read
the comment for more description.
